NEEDLE-MAGAZINE AND FEEDING DEVICE FOR SOUND-BOXES.
Specification of Letters Patent.
Application filed October 15, 1919. SerialNo. 330,744.
To all whom it may o'oncem:
Be it known that I, JACOB JoNEs, a citizen of the United States, residing at Ringling, in the county of Meagher and State of Montana, have invented certain new and useful Improvements in Needle-Magazines and Feeding Devices for Sound-Boxes, of which the following is a specification, reference being had to the accompanying drawings. v
This invention relates to a needle or stylus magazine and feeding device, particularly adapted for use in connection with sound boxes of talking machines, and an important general object of the invention is the provision of means for containing a plurality of needles, and a device for operating said means, whereby a needle at a time may be conveyed through the channel or duct to the stylus holder of the sound box.
Another object of the invention is to provide a device of this kind wherein the stylus or needle holder is provided with means for guiding the needle or stylus into position, so that it may be secured in place by the usual set screw of the holder.
A further object of the invention resides in the provision of means, such as a stool for limiting the needle in its proper position in theholder, so that it may be clamped by the set screw.
Furthermore, it is the aim to provide a limiting stop or stool or support for the needle, including means, whereby the screw or stop is capable of being adjusted, relatively to the needle, so as to hold the same in difiierent adjusted positions relatively to the holder. 1
Heretofore in talking machines, it ha been customary to either lift the tone-arm or partly invert the sound box, to permit the insertion of a needle or stylus into the holder. In the present invention, it is the aim to avoid raising the tone-arm or inverting the sound-box, and instead to provide means for containing a pluralty of needles and feeding one at a time to the holder.
While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.
The invention comprises further features and combinations of parts, as will be hereinafter set forth, shown in the drawings and claimed.
In the drawings:
Figure 1 is a view in side elevation of a portion of a talking machine cabinet showlng a part of the tone-arm and the sound box at its free end, with a stylus or needle projecting from the holder and engaging a stool or support, showing the magazine and its guide channel in section longitudinally.
2 is a plan view of the same.
Fig. 3 is a vertical sectional view on line "Patented Nov. 9, 1920.
3-3 of Fig. 1, showing the magazine and thechannel or duct leading from the channel guide for the magazine terminating down toward and adjacent to the holder for the stylus or needle, also showing the needle engaging the support or stool.
Fig. .4 is an enlarged detail view of the lever for shifting the magazine.
Referring more especially to the drawings, 1 designates a tone-arm of a talking machine and 2 denotes the usual sound box connected to the tone-arm. The sound box is provided with a conventional form of needle or stylus holder 3, which has a longitudinal bore 4 to receive the. needle or stylus 5, there being a set screw 6 threaded transversely of the holder to engage the needle for the purpose of binding the same in the bore. The holder is open at its upper end as shown and terminates in a funnel shaped portion 7, so that the needle or stylus which may be dropped or passed through the upper part of the holder may be guided to and through the bore. In this application there is disclosed a type of talking machine, wherein the tone-arm is so mounted as to support the lower end of the holder of the sound boX a spaced distance from the stool or support 8, so that when a stylus or needle is dropped through the upper end of the holder, the point of the needle will contact with the upper end of the stool or support, so as to limit the needle or stylus in its proper position, so that it may be held firm by the set screw. This stool or support comprises a plate 9 which is secured to the cabinet of the machine by screws 10 and up wardly from which the cylindrical projection stool 8 extends. A cap 12 is threaded to the stool, and is provided with a depression 13 on its upper face, to be engaged by the point of the needle. It will be noted that the projection is inclined axially with the Inclination of the needle or stylus projecting from the holder. Itis obvious that by adjusting the cap wlnch is threaded to the projection, it may be adjusted relatively 4 to the lower end of the holder, inorder to limit the needle, and hold its record engaging point relatively to the holder, that is to say, in difi'erent adjusted positions. By means of this stool or support, it'is possible that either a. long or short portion of the needle may be allowed to project from the holder. Furthermore, by providing a holder with an upper open end funnel "shaped, the necessity of lifting the tone-arm or invert-' ing the sound box to place a needle or stylus in position is eliminated, particularly since it is the aim to afford means for limiting the needle or stylus in position.
Secured-to the peripheral edge of the casing of the sound box is a pair of laterally extending arms 17, which in turn are secured to an elongated magazine support 19. This magazine support 19 has a longitudinally elongated guide channel 20. A 'needle or stylus magazine 21 is provided and it has an elongated reduced guide rib 22 on its under surface engaging the channel 20 of the magazine support 19. The needle magazine comprises a body provided with a p rality of vertical parallel bores or openings 23, which receive a plurality of needles, the
points of which extend downwardly, and 611."
gage thebottomof the channel of the support. A tubular guide 24 is integrally connected to the magazine support and communicates with the channel of the support, so that when the magazine is moved intermittently a needle at ,a time willautomatically,
throu h the medium of gravitation, drop into t e tubular guide, that is to say when the respective opening or bore of the magazine registers with'the passage through the tubular guide. The upper edge of the side of the body of the magazine is provided with a plurality of ratchet teeth 26, which are cooperated with by the nose of a dog 27, which is pivotally mounted on a manually actuated lever 28. The lever 28 is preferably, though not necessarily, constructed of a singlepiece of sheet metal, bent to form a loop 29, which straddles the magazine sup- .gort, and is pivotally connected thereto.
ne'end of one of the sides of the loop of the lever is extended, forming a handle 30,
which may be grasped by the fingers, to move the lever, .so that the nose. of the dog will operate themagazine. The dog is pivoted at '31 to one of the sides of the loop of the lever, so that the nose of the dog will be in. a position to engage any one of the ratchet teeth to adjust the magazine. A suitable bowed leaf spring 32 is so connected to the dog and to one of the. arms of the loop of the lever as shown, tohold the nose of the dog in constant position adjacent the ratchet teeth of the magazme support. A portion of the bowed leaf spring projects at the rear beyond the, tail of the dog, and is provided with a loop or arch hook 32, whlch is engaged by an eye 33 of a rod 34:,
. which passes through an opening inthe upper part of theloop end of-the loop, in order to guide the rod when the dog is in action. It will be noted that by grasping the upper end of the rod and pulling upon it, the nose of the dog may be forced into engagement with any of the teeth of the magazine. .However, by depressing upon the upper end of the rod, it will be observed that the spring projecting beyond the tail of the dog will yield, and the nose of the dog will be raised out of engagement with any' one of the teeth of the magazine, so that the magazine may be moved in either direction very quickly by raising the dog out of engagement with the teeth, or may be moved intermittently as the lever is oscillated or rocked upon its pivot. I
In order to permit the rod 34: to manipulate the bowed leaf spring 32 and the dog 27 for the purpose-of attaining the result above mentioned, the bowed leaf spring is connected in any suitable manner as at 27* to the dog 27. This connection may be made by a drop of solder as indicated, or any other suitable. means may be employed. By attaching the spring to the dog in this manner, the dog may be operated to engage or disengage the teeth of the rack by first pulling upwardly on the rod 34:, and il y then pushing downwardly on the rod 34;. he dog 27 will operate as above stated, owing to one arm of the leaf spring extending beyond the pivot 31 of the dog,so that'pressure on the arm will raise the dog, or a pull upon the arm will cause the dog to move downwardly and engage the teeth of the rack.
In the operation, the operator first loosens the set screw of the holder, so as to support, The lever is then operated which,
by means ofthe nose of the dog, will impart an intermittent movement to the magazine.-
When one of the openings or bores of the magazine registers with the passage of the tubular guide, the needle contained in the bore or opening will automatically by gravitation drop through thetubular guide, and
by virtue of the funnel of the holder, the needle will drop into position, after which sald screw of the holder may be tightened and the needle held in place. The support or stool is adjusted, according to the length of the portion of the. needle to project from the holder.
